### Agent-workflow platforms that can run a coding step

- **[Sim](https://www.sim.ai/)** is an [Apache 2.0-licensed](https://github.com/simstudioai/sim) agent-workflow platform in which custom code can run as one step in a larger process. You can describe a workflow with [Chat](https://docs.sim.ai/chat/workflows) and add custom JavaScript through a [Function block](https://docs.sim.ai/workflows/blocks/function).

- **[Gumloop](https://www.gumloop.com/)** is a hosted, no-code automation platform. Gumloop's [agentic AI tools roundup](https://www.gumloop.com/blog/agentic-ai-tools) describes how it fits alongside tools such as Cursor, n8n, and Zapier. Check Gumloop's official site for current pricing.
- **[n8n](https://n8n.io/)** is a fair-code, self-hostable workflow platform with a visual canvas and a [code step](https://docs.n8n.io/integrations/builtin/core-nodes/n8n-nodes-base.code). [n8n's pricing page](https://n8n.io/pricing) lists cloud Starter at €20 per month billed annually with one shared project. Pro costs €50 per month billed annually, while Business costs €667 per month billed annually. Business includes self-hosting, SSO, SAML, LDAP, and Git-based version control. Enterprise pricing is custom. The self-hosted Community Edition is free under [n8n's Sustainable Use License](https://docs.n8n.io/privacy-and-security/sustainable-use-license/).

Yes, but the tools in this article use different license models, including proprietary, source-available, and open-source licenses. Many prominent in-IDE coding agents, including Cursor, Windsurf, and Claude Code, are proprietary applications.

Licensing varies more among workflow platforms that can run code. n8n uses its [Sustainable Use License](https://docs.n8n.io/privacy-and-security/sustainable-use-license/), which is source-available and includes commercial restrictions. Sim's core uses the permissive [Apache License 2.0](https://github.com/simstudioai/sim), and our documentation provides [self-hosting guidance](https://docs.sim.ai/self-hosting).

## Where does Sim fit between an AI agent marketplace and custom development?

Sim fits between fixed marketplace agents and fully custom development by giving teams a visual way to build and adapt agent workflows while retaining access to an Apache 2.0 codebase.
Sim fits between fixed marketplace agents and fully custom development by giving teams a visual way to build and adapt agent workflows while retaining access to an Apache 2.0 core codebase.

Sim is most relevant when a team wants the speed of a builder but does not want its core workflow confined to an opaque marketplace listing. Teams can use reusable workflow patterns as a starting point, then define the tools, data flow, model interactions, conditions, and controls required by their own process.
